Question

the density of oxygen is about 1.429 times 10^negative 4 grams per liter. which number is higher than 1.429 times 10^negative 4 ?

4.129 times 10^negative 4
4.129 times 10^negative 5
4.129 times 10^negative 3
4.129 times 10^negative 6

Answer 1

To determine which number is higher than \( 1.429 \times 10^{-4} \), we need to compare each option by converting them into a similar form for easier comparison. Here are the comparisons:

1. **\( 4.129 \times 10^{-4} \)**: This is clearly higher than \( 1.429 \times 10^{-4} \) because \( 4.129 > 1.429 \) when both are multiplied by \( 10^{-4} \).

2. **\( 4.129 \times 10^{-5} \)**: This is \( 0.04129 \times 10^{-4} \) (by moving the decimal point one place left), which is lower than \( 1.429 \times 10^{-4} \).

3. **\( 4.129 \times 10^{-3} \)**: This value is equivalent to \( 412.9 \times 10^{-4} \) (by moving the decimal point two places right), which is much higher than \( 1.429 \times 10^{-4} \).

4. **\( 4.129 \times 10^{-6} \)**: This is equivalent to \( 0.00004129 \times 10^{-4} \) (by moving the decimal point two places left), which is also lower than \( 1.429 \times 10^{-4} \).

Based on this analysis, the numbers that are higher than \( 1.429 \times 10^{-4} \) are:

- \( 4.129 \times 10^{-4} \)
- \( 4.129 \times 10^{-3} \)

So the answers are \( 4.129 \times 10^{-4} \) and \( 4.129 \times 10^{-3} \).
